Analysis of the anthropogenic environmental risks and their evaluation regarding future climatic changes for the metropolitan Buenos Aires region

The purpose of this paper is to compare possible effects of climatic changes (precipitation and sea level variations) with the anthropogenic changes along the coast of Buenos Aires city. An increase in the accumulative precipitation of 4.1 mm per year since 1960 was detected, as well as a climatic t...
